Craftland

when I was in the shadow skylands doing a region, I got a strange bug when creating the region, the sky went really bright, the region marker went black, the background of my chat went completely clear and lots of other things ended up going fairly dark. Here is a screenshot:

I did /crashme with these things and it came up with this: https://gyazo.com/e3a8b799fad8eabb234a6fb565a01752
